[GUI] Dynamic sizing.

Hello Everyone, It seems that right now the easiest and best way to deal with dynamic sizing of widgets is as follows: -- CGA/CommonAttributes.hs class HasSize w where size :: Attr w SizeType data SizeType = Fixed (Int,Int) | Standard Where fixed is obviously the pixel size and Standard is some implementation dependant size. For example, a button would likely have a fixed height and a length based on the label size on a macintosh. What does everyone thing about this? It is pretty elegant and simple this way so it makes me think that more "stuff" needs to be added. David J. Sankel
